Modal Parameter Identification

The accurate identification of modal parameters is the core content in the experiment modal analysis of structure. The effective and accurate collection of vibration dates comes to be as the premise of high precise identification. This paper presents a new method of data collection in modal parameter identification. By high-speed camera, time series images of vibration were obtained; Then, the images collected were processed using digital image correlation method, and the time-displacement graphic on vibration direction of some pixels selected was got; Finally ,the time-domain signal was post-processed based on the complex Morlet wavelet transform, and the modal parameters were got. By a specific experiment, the method was proved feasible and effective.
